The Cu-N distance is 2.032(2) A and the Cu-Br distance 2.3521(5) A. Heating a CH2Cl2 or acetone solution of 1 resulted in complex 2, which consists of a slightly distorted tetrahedral [Cu(dpp)2]+ cation and a linear two-coordinate [CuBr2] anion. 2 crystallizes in the triclinic ...
A new mixed-anion crystal composed of BEDT-TTF radical cation salt [BEDT-TTF]2(CuBr2)0.4(CuCl2)0.6 with an α'-type donor arrangement with a formal charge of +0.5 per BEDT-TTF was prepared by using a chemical oxidation method and characterized by using X-ray diffraction, four-probe ...
The antiferromagnetism is explained by the coupling of the spins of two Cu2+ ions in the anion with an exchange constant of J = -18 cm-1. The CuI and CuII atoms are clearly distinguishable in the mixed valent anion. The OMTTF cation is not planar but exhibits an interplanar angle ...
